Specification of Letters Patent.

Patented J one 2, 1914;.

Application filed August 2, 1912. Serial No. 712,907.

To all whom it may concern Be it known that I, EDWARD J. F. REA, acitizen of the United States, residing at Hartford, in the county ofHartford and State of Connecticut, have invented certain new and usefulImprovements in Planting- Presses, of which the following is a SPGC1l1-cation.

This invention relates to printing presses and especially to a means foroperating a form-carrier, one of the principal objects of the inventionbeing to provide simple and effective means of the character indicatedby which a form can be caused to move toward and from the printingplane.

In the drawings accompanying and forming part of the presentspecification I have shown in detail one of the several convenient formsof embodiment of the invention, which I will set forth in detail inthe'following description, this showing being prlmarlly provided toenable those skilled in the art to practise the invention. It will beclear that I do not restrict myself to such disclosure; I may departtherefrom in several respects within the scope of the invention definedby the claims following said description.

Referring to the drawings: Figure 1 1s a top plan view of bed mechanismlnvolving my invention. Fig. 2 is a longitudinal section on the line 2 2of Fig. 1. lilg. 3 is a somewhat similar view, some of the parts beingomitted and certain additional parts being illustrated. Figs. 4 and 5are transverse sections on the lines 4li and 5-5 respectively of Fig. 1.Fig. 6 is a longitudinal section on the line 6-6 of Flg. 1.

Like characters refer to like parts throughout the several figures,which it will be observed are on different scales.

The machine shown involves in its organization a traveling bed as 10which reciprd cates in the present instance, in a horizontal path afterthe manner substantially shown in Letters Patent No, 843,535, grantedFebruary 5, 190? to James W. IIoag, to which reference may be had. Thisbed is supported by complemental side rails as 11 sustained after thecustomary practice, by the frame work (not shown) of the press. Itshould be noted at this point that one of the primary purposes of thepresent invention is the shifting of a form-carrier by which the form ortype can be carried toward and from the printing plane or zone, andpreferably,

although not necessarily the form-carrier is movably mounted upon thebed 10 and at proper points in the travel thereof is caused to rise andfall. It is conceivable, of course, that the form might be stationaryupon the bed, and in this event the bed itself would be shifted inaddition to its traveling movement as a matter of fact it is notessential that the form be upon the bed, although this is advantageous.A form carrier such as meets my conditions is that denoted in a generalway by 12 and as shown, it is disposed within the bed 10 which may asillustrated be of substantially rectangular shape. This carrier 12 inthe showing made, sustains the form which may be of any suitable nature,and it is caused to move in alternation, by wedge means as willhereinafter appear, upwardly and downwardly, the first mentionedmovement being accomplished to secure an impression upon paper carriedby a cylinder (not shown), the type or form being inked when the bed isin an upper position. The bed and form-carrier and their movements aswill be inferred, are fully set forth in the Letters Patent to which Ihave alluded, and therefore require no further description.

As already intimated the form-carrier 12 is raised and lowered by wedgemeans and in the organization represented this wedge means comprises acarrier such as the saddle denoted in a general way by 13 and which isillustrated :is made up of companion sidebars 1 1 and a cross-bar 15united with the side bars between the ends thereof, the saddle as awhole being of approximately H- form in plan. The bed 10 is providedinteriorly thereof with inwardly-extending flanges or webs 16constituting suitable supporting means for the side-bars 14, althoughsaid sidebars as illustrated, do not directly rest on said flanges,being directly supported by the duplicate plates 17 fitting in channels18 in the upper sides of the two supporting flanges 16, and borne byadjusting screws 19 tapped through said flanges. The several adjustingscrews 19 of which there may be any suitable number such as two at eachside, can be utilized to accurately adjust and level the saddle 13. Aswill hereinafter appear the saddlel3 is shifted with respect to the bed10, and during this relative shifting movement the wedge means to whichreferenee has been briefly made, acts to cause the rising and falling ofthe form-carrier 12 on or in the bed.

The side-bars 1 1 are shown provided at or near their opposite ends withwedges 2O suitably fastened thereto, while the formcarrier 12 hassimilarly fastened to its under side, coiv'perating wedges 21, therebeing as shown four wedges on the saddle 13 and a corresponding numberon the formcarrier 12, the two sets of wedges as will be understoodcoacting to effect the rising and falling of the form carrier. Thewedges in addition to their bevel or angular faces also have horizontalor rest portions. As will hereinafter appear the form-carrier 12 hasthree distinct positions, and when in the upper and intermediatepositions the type or form is inked, so that when the form is moved fromthe intermediate position to the upper position, an impression of theinked form upon the sheet or equivalent carried by the cylinder is made.I might add that when the form carrier is in its lowermost position theform is not inked; the inking mechanism, however, forms no part of thepresent application. I will also hereinafter describe the means foroperating the wedgecarrier or saddle 13 with respect to the formcarrier,although I might note at this time that if the saddle 13 be moved to therightin Fig. 2 the form-carrier 12 through the cooperating sets ofwedges 20 and 21, will be raised whereas when the saddle is moved in theopposite direction the form-carrier automatically lowers. Theform-elevating movement is accomplished in the present instance, fromthe power-shaft of the machine, while the opposite throw is secured byspring means. The power-shaft is denoted by 22 and fastened to it is aspur-gear 23 which receives motion from a pinion, (not shown). Thespur-gear 23 is illustrated having a wrist or crank pin 2a to which isloosely jointed the inner end of the connecting-rod or pitman 25, havinga pivotal connection with the stub-shaft 26 supported by the bracket 26on the bed 10, said rod having at or near the shaft 26 the crank arm 27,the purpose of which will be hereinafter explained. It will be evidentthat as the spur gear or its equivalent 23 rotates the rod 25 and hencethe bed 10 will be reciprocated and also that the arm 27 will be rockedor oscillated. Said arm 27 terminates in a cross head 28 to which areshown pivoted similar links 29 jointed at their inner ends to pivots orjournals 30 extending laterally from the block 31, the wedge saddle 13being provided with bearings 32 having suitable ways for supporting saidblock 31 and a companion block 33 for horizontal sliding movement. Tothe journals 30 are pivoted the links 3% likewise connected with therocker 35 between the ends of the latter, the upper portion of saidrocker being bowed or cranked for the passage of the connecting rod 36,the purpose of which will be hereinafter explained. Rigidly fastened tothe upper end of the rocker 35 are the journals 3?, the bed 10 havingsuitable bearings to receive said journals 37 for oscillatory motion.Pivoted in a forkat the lower end of the rocker 35 is a link 38 likewisejointed to the reciprocatory block 33. It will, therefore, be apparentthat when the shaft 26 is rocked the blocks 31 and 33 through thedescribed connections therewith will be simultaneously reciprocated andthat the amount or degree of movement of the block 33 will be greaterthan that of the block 31 for a purpose that will be hereinafterobvious. When at least one of said blocks is locked to the saddle, thesaddle will be operated in one direction by and on the movement of saidblock, return movement of the saddle being accomplished by independentmeans.

To lock the blocks to the saddle I have shown latch mechanism comprisingthe latches 39 and 10, the latch 39 being constantly active duringprinting or normal operation of the press, while the latch 10 is merelyemployed when the press is to be thrown into action being inoperativeduring printing, although as will hereinafter appear said latch 4:0 maybe operated to shift the complemental latch 39 to a releasing positionwhen the form raising mechanism is to be put into an inactive relation.The latch 10 is shown as rigid with the shaft 41 supported for rockingmotion by the bearings 32, the latch 39 being loosely mounted on saidshaft 4:1 and being movable to blockengaging position by a spring d2connected therewith and also with some suitable relatively fixed part ofthe saddle or form-open ating member 13. The latch 40 is also springoperable, the spring 4-0 (Fig. 4.) connected with the arm 10 on theshaft 11 being shown for such purpose. It is possible, of course, that Imight employ but a single block and a cooperating latch or theirequivalents, but by duplicating the same I can prevent lost motion andinsure smoothness of action of the wedge-saddle 13 and the form carrier.

As already intimated during printing, the power-operable block 31 whenlatched to the saddle 13 the latch or pawl serves to move said saddle 13in one direction. The rod 36 connected rigidly with the saddle 13 and towhich I have already referred, plays a part in effecting the returnmovement of the saddle, the power operable block 31 and latch 39 in thepresent instance normally advancing the saddle 13 or moving the same tothe right in Fig. 2, while the rod and its adjuncts, retract saidsaddle. The rod 36 extends into the tube or casing 43 rigidly mounted011 the bed 10 and to the forward end of said rod is connected one endof the coiled spring 44: in said casing, the opposite end of said springbeing connected with a pin 45 projecting through the forward wall of thecasing or tube 13 and held against displacement by the holding and checknuts 1:6. It will be assumed that the parts (except the latch 10) areoccupying the positions indicated in Fig. 2, the latch 39 being inengagement with the block 31 and the arm 27 being at its extreme leftthrow. As said arm 27 moves toward the right, the block 31 through itsdescribed connections therewith is carried in a similar direction andengaging the latch 39 moves the saddle 13 tl'ierewith, the spring -11being stretched during such action. XV hen the arm 27 completes itsstroke to the right the spring ll will return the wedge-saddle 13 to itsprimary position, at which time the arm 27 is moved toward the left bythe shaft 22 as already set forth. As the saddle 13 is advanced the form12 is raised, said form dropping on the return or opposite movement ofthe saddle.

The shaft 1-1 to which the latch 41:0 is keyed, is shown having rigidtherewith a lever or arm 50 which may as shown be equipped with ananti-friction. roller 50 adapted as the saddle 13 reciprocates to travelupon a rail or way 51 which as will hereinafter appear has threedistinct positions. Said rail is shown having near its opposite ends camslots 52 through which extend projections 53 on the framing of themachine and as also having a pin 5-1 adapted to enter the fork of therock lever 55 supported on said frame and adapted to be actuated in anydesirable manner.' The rail 51 is shown as occupying its lowermostposition in Fig. 2. By swinging the arm or lever one step to the rightsaid rail will be elevated to the position it occupies duringprii'iting, and by moving said lever or arm a second step said rail.will be elevated its maximum extent to thereby move the latch 10 toblock-releasing or ineifective position said latch. a0 when thusoperated, moving the latch 39 to blocloreleasing position so that theblocks 31 and 33 can be operated with respect to and on the saddle inwhich event the latter will not be shifted but will remain relatively atrest, this latter relation being assumed when the form-elevatingmechanism is to be thrown out of action. The latch 10 is shown furnishedwith an extension 56 adapted to engage the pin 57 on the cotiperatinglatch 39 when the form-opcrating mechanism is to be thrown out ofaction.

it will be understood that when the formelevating mechanism is out ofaction, (the saddle 13 at this time being at rest notwithstanding thefact that the shaft 26 is being rocked,) the rail 51 will be in itsuppermost or tripping position to which it has been moved by the rockarm 55, acting through the primary agency of a hand lever (not shown).As said rail 51 is moved to said uppermost position, it lifts the latch10 to its eXtreme uppermost or third position and as the latch 10 isthus operated the extension 56 thereon, moves the latch 39 to itstripped position, the consequence being that the two blocks 31 and 33will reciprocate idly on the saddle 13, without actuating the latter asboth latches are tripped. In said Fig. 2, however, the saddle 13 is notat the extreme end of its retractive or backward stroke, it beingassumed that said saddle is being moved in said direction by the springli. With the two latches tripped they with the saddle will occupy aposition somewhat to the left of that they are shown as occupying inFig. 2. To throw the fornrelevating mechanism into action therefore, thefollowing procedure will be adopted: The rail 51 will be moved to itslowermost position so that the spring 10 can pull down the latch 40 tothe full line position in Fig. 2 and at the same time the latch 39 willbe moved by the spring 12 to block-engaging position. As alreadyintimated the saddle 13 is now at the extreme end of its retractive orbackward stroke; when it is there is considerable space between theblock 33 and the latch 10. As the arm 27 swings to the right the twoblocks 31 and 33 are carried therewith until. the block 33 comes incontact with the latch 10 at which point the saddle 18 is moved forward.When the two blocks and saddle have nearly reached the front end of thestroke, the latch 39 is moved behind the catch portion of the block 31,the active portion of said latch 39, however, being carried a shortdistance beyond the catch portion of said block 31 so as to insureproper latching, this condition being due to the fact that the stroke ofthe block 33 is greater than that of the block 31, said latch 39 beingcarried to said particular position through the joint action of theblock 33 and latch 40. As soon as the active portion of the latch 39 isin position to engage the catch portion of said block 01 the latch 10 iselevated to its central position. On the back stroke of the saddle thelatch. 39 comes in contact with the block 31 causing a slight knock. Toeliminate this knock the latch -10 is elevated to its center orintermediate position or that it occupies during printing as shown bydotted lines in 1* 2 at which time the extension 56 rests against thepin 57. When the latch is in said central position it is out of the pathof the cooperating block 38. During printing, therefore, the block 31and latch or pawl 89 are in action, it being evident that at this timethe rail 51 is in its central position, being adapted as it is movedfrom its lowest to its central position to elevate said latch 4-0 to thedotted line position in Fig. 2. By moving the rail 51 to the third oruppermost position, the latch 4,0 is further lifted, thereby depressingthe latch 39 and disengaging the same from the block 31, so that whenthe block 31 and companion block 33 are advanced they will not 0 aerateor advance the saddle 13, the result being that the form elevatingmechanism is thrown out of action. The block 33 and cooperating latch orpawl 4L0 present therefore a convenient means for automaticallypositioning the latch or pawl 39 with respect to the block 31, and itwill be understood that after said block 31 and pawl 39 are thusrelatively positioned, the latch 40 is thrown out of action or moved toits intermediate position as shown by dotted lines in Fig. 2. It shouldbe explained that said latch 10 has three positions, the lowest positionbeing shown by full lines in Fig. 2, and the intermediate position bydotted lines in the same view. \Vhen said latch 40 is in its thirdposition it trips, as already described, the companion latch 39. Thelatch 39 has merely two positions, one an operative position when it isin the path of the block 31, and the other a trip or releasing position.It should be noted that the form is elevated when the parts are in theirforward positions, while it is caused to lower when they are in theirbackward positions. By forward motion I mean the movement of the bed 10and form carrier 12 toward the right in Fig. 1, the backward movementbeing just exactly opposite to this.
